Summary

This study looks at whether leaving a stent out after kidney stone surgery can reduce pain and the need for extra medical visits. About 184 adults with kidney or ureteral stones will be randomly assigned to either get a stent or not after their procedure. Researchers will track pain levels and how often patients need follow-up care over 30 days.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: stent omission vs. stent placement
What this could lead to: If successful, this could show that skipping a stent after kidney stone surgery reduces pain and healthcare visits without increasing complications.
What could go wrong: This is a relatively small, early-stage study. Results may not apply to all patients, and skipping a stent could lead to unexpected problems in some cases.
